- Geo log i cal and geotechnical en gi neer ing field tests, like struc ture drillings and dy namic (DPL, DPSH) or static probing (CPT), are con sid ered for a fun da men tal source of in for ma tion about soil and wa ter en vi ron ments. Since Eurocode 7 has been in tro duced, it has be come more com mon to use also dilatometers (DMT) or pres sure me ters (PMT). Re sults ob tained us ing all the men tioned tests are al ways of a dis crete na ture – in for ma tion is pro vided in cer tain points in the field. How ever, they de ter mine the ba sis for cre at ing spa tial mod els of geo log i cal struc ture and geotechnical con di - tions of a sub stra tum. The range and num ber of in ves ti ga tions con ducted (in clud ing drill ing, prob ing and lab o ra tory tests) in flu ence pre ci sion, in which a geo log i cal struc ture is iden ti fied and thus, also af fect prob a bil ity of com pat i bil ity be tween spa tial model and real geo log i cal con di tions of a sub stra tum. In the pa per, re sults of non-in va sive elec tri cal re sis tiv ity to mog ra phy (ERT) method are pre sented, com pris ing 2-di men sional im age of a soil me dium re sis tance.

In ad di tion, when com bined with drill ing re sults, it can be used to ac cu rate de ter mi na tion of bound aries be tween soil lay - ers. Car ry ing out of ERT tests in the field dur ing ex press way con struc tion con trib uted to iden ti fi ca tion of weak, low-strength soils like or ganic soils (peat, aggradated mud) and of soft con sis tency co he sive soils. These kinds of soil are the main cause for un ac cept able de for ma tions ap pear ing in the new road en gi neer ing struc ture.
